Deepwater Horizon Background
Largest accidental oil spill in U.S. history On April 20, 2010 drilling rig exploded, followed by fire and sinkingExplosion killed 11 platform workers and injured 17 othersLeak was largely stopped by capping the gushing wellhead on July 15 after releasing about 4.9 million barrels of oil

Explosion and Fire
Sinking
Deepwater Horizon:Some Numbers
Estimated oil flow rate of 35,000-60,000 barrels per dayTotal oil/gas recovered/flared to date: 771,283 barrels of oil and 1,729.6 million cubic ft of gasPersonnel: 46,271Boom deployed: 9,354,842 ftDispersant use: 1,776,995 gals (1,071,315 surface/705,680 subsea)
672 miles of shoreline impacted

NIOSH Objectives
To provide opportunity for every response worker to be counted
To prevent illness and injury real-time during the event by reducing or eliminating exposures
NIOSH Activities

NIOSH HEALTH HAZARD EVALUATIONS
Evaluated Workers at the Source
In-Situ Burns
Dispersant Use
Containment Boom
20
Decontamination of Vessels
Health Hazard Evaluations: Six Work Categories
On Shore Evaluations: Beach clean-UpWildlife rehabilitation Equipment decontamination and waste stream management
Off Shore Evaluations:Source ControlIn-situ burnsBooming, skimming, dispersant operations
HHE staff at source control
Health Hazard Evaluations
Additionally, Psychological Stress/Work Organization Focus Groups Conducted with Safety Officers
Note: HHE Interim reports #1 through #5 available on NIOSH website; remainder of
reports forthcoming

Chemical Exposures: Crude/Weathered Oil/Dispersants
Oil and/or dispersants were noted as a contributing factor in 13 casesAll were treated by first aid aloneNine occurred offshoreSix cases were dermatologic in nature, four led to injury (such as slipping on oily surface), and three were attributed to oil or dispersant vapor exposure
Heat Stress
141/192 (73%) heat stress cases occurred “onshore” 110 of these occurred among laborers such as beach cleanup workers, boom decontamination workers, heavy equipment operators, and general laborers
Toxicity TestingAcute animal testing (rats) to be conducted on:
Dispersant (Nalco Corexit 9500A)Crude Oil from the source (sample from well head obtained May 23rd)Dispersant/crude oil mixture
Inhalation studiesMeasuring pulmonary, cardiovascular, and CNS outcomes
Dermal studiesAssessing hypersensitivity and immune-mediated responses
